“Prince Charles does it, Prince Harry does it and even little Prince George has been seen doing it, but Meghan might be the first royal woman to shove her hand into a pocket when she’s out in public,” she said.

James explains that typically placing a hand in the pocket is an indicator that someone wants to hide.

“The classic reason for this very common gesture is that it signals a subliminal desire to hide, especially when the hands are shoved deep into the pockets,” said James. “It also helps get over the common problem most of us suffer from, which is not really knowing what to do with our hands when we know people are looking at us.”

But the expert doesn’t believe this is why the Duchess has taken to the pose.

Instead, James believes her common gesture has everything to do with Markle’s style inspiration.

“Meghan’s high levels of confidence suggest her reason is more to do with fashion than anxiety though… It is also a probable nod to her love of ’50s styling,” she said.

“Her full skirts are very Audrey Hepburn and, to wear them well, a hand in one pocket is almost de rigueur. She also loves slouchy coats and jackets and the same fashion rule of ‘wearing’ the tailoring would apply with them too.”
